Manufactured from hardened tool steel, it holds a parallelism tolerance of 0.0003 inches across its 6-inch length, making it a reliable reference and support tool for milling, grinding, and inspection operations. The parallel measures 6 inches long, 1-3\/4 inches high, and 3\/16 inches thick. Hardness is rated at 55-62 HRC, ensuring resistance to wear and deformation under repeated clamping loads. Machinists and toolroom professionals use these to level workpieces, establish reference surfaces, and support parts in vises or on surface plates.\u003c\/p\u003e\n\u003cp\u003eThis two face parallel is suited for toolroom, job shop, and production machining environments where accurate workpiece positioning is required. It supports setups in vertical milling machines, surface grinders, and inspection fixtures. Sold as an individual unit, it can be added to an existing parallel set or used as a standalone reference tool where its specific thickness or height is the required stack dimension.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eParallelism of 0.0003 inches ensures consistent, repeatable workholding accuracy\u003c\/li\u003e\n  \u003cli\u003eHardened tool steel construction at 55-62 HRC resists wear and maintains dimensional stability\u003c\/li\u003e\n  \u003cli\u003eTwo face ground parallel surfaces provide reliable reference contact on both sides\u003c\/li\u003e\n  \u003cli\u003eAccuracy to 0.001 inches suits a wide range of precision setup applications\u003c\/li\u003e\n  \u003cli\u003eSquareness of 0.0003 inches per 6 inches supports use as a right-angle reference surface\u003c\/li\u003e\n  \u003cli\u003eCompact 3\/16-inch thickness useful for tight-clearance vise setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard two face parallel for use in machinist vises, surface grinders, and inspection fixtures common to toolroom and production machining environments.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eParallels are installed by machinists and toolroom technicians as part of workholding setup. Clean the vise jaw faces and parallel surfaces before use to prevent debris from affecting seating accuracy. Do not use parallels as striking surfaces or pry tools, as this can damage the ground faces and compromise parallelism. Inspect periodically for nicks or surface damage that could affect workpiece support accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eParallel Type\u003c\/strong\u003e: Two Face\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1-3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Tool Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eParallelism\u003c\/strong\u003e: 0.0003 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquareness\u003c\/strong\u003e: 0.0003 inches per 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 0.001 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 55-62 HRC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 637-7507\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51715513188658,"sku":"637-7507","price":77.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/81608a4be40c88220f67e480fa7858da.jpg?v=1788515007","url":"https:\/\/voomisupply.com\/products\/value-collection-637-7507-two-face-parallel-tool-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
